A 22-year-old motorist was killed in a two-vehicle crash in Agua Dulce, authorities said this week.

The crash occurred at 6:25 p.m. Monday on Ward Road, west of Sierra Highway and involved a 1997 Toyota driven by the 22-year-old man, and a 52-year-old motorist in a 2016 Ford with a loaded trailer, according to the California Highway Patrol.

The Toyota driver was heading west on Ward Road and passed the Ford near Sierra Highway, then slowed and began to steer toward the right curb as if he was going to stop.

The Ford driver, seeing that the Toyota was pulling to the right and slowing, changed to the number one lane and accelerated to about 40 mph, as it began to pass the Toyota.

For unknown reasons, the Toyota driver accelerated from the right curb, turned left across the number two lane and directly in the path of the Ford, according to the CHP.

The motorist in the Ford applied the brakes, but still struck the left side doors of the Toyota, causing the Toyota to move across two eastbound lanes of Sierra Highway.

The Toyota driver, who was a resident of Palmdale, was airlifted to Antelope Valley Hospital, where he died from his injuries. He was the lone occupant in his vehicle. The Ford driver was uninjured.

It was not immediately known if alcohol or drugs contributed to the crash.
